Abstract

Based on the results of observations, it shows that the development of student worksheets is not optimal, especially in science learning with water cycle material which should be adapted to developments in the 21st century, as science learning is fun learning if it is created well. The 21st century requires students to have various skills, one of which is critical thinking skills. because students are required to be more responsive in analyzing, solving problems and solving problems in the learning process. The aim of this research is to develop and determine the feasibility of STEM-based student worksheets with water cycle material for fifth grade elementary school students. This research method is Research and Development (R&D), which is a research method used to develop or validate products used in education and learning. The results of the research show that the process of developing student worksheets to train critical thinking skills consists of three stages, namely preliminary study, product development, and test the product. The student worksheets were validated by three expert validators, namely design expert validation, material expert and language expert with respective scores of 84.37%, 94% and 91.42% with very feasible criteria. So, it can be concluded that this STEM-based student worksheets with water cycle material is suitable for use as a learning companion for students to improve students' critical thinking skills KEYWORDS

Abstract

In the learning process in the classroom, the conventional learning model is still used, where the teacher only plays the role of conveying information, while the students are passive listeners. This study aims to produce inquiry-based interactive multimedia that has been tested for media feasibility and has been proven effective in improving cognitive, affective, and psychomotor learning outcomes in fifth-grade students of Pancasila education at SDN 056425 Damar Seratus. The type of research used is Research and Development (R&D), commonly referred to as research and development. The development design in this study uses the Analysis Design Development Implementation Evaluation (ADDIE) model. The subjects of the research are fifth-grade students of SDN 056425 Damar Seratus. The results of the validation by media experts, design experts, material experts, education practitioners, and the results of field trials (individuals and small groups) indicate that the developed media products are suitable for use and categorised as very good. The Inquiry-Based Interactive Multimedia product in the form of Articulate Storyline 3 developed is also effective for use. The effectiveness of the developed media products is evidenced by the N-Gain test, which yielded a result of 0.6, and the hypothesis test, which yielded t-count = 8.286 and t-table = 1.705, thus t-count > t-table, leading to the acceptance of Ha and rejection of H0. In addition to being effective in improving cognitive learning outcomes in students, this inquiry-based interactive multimedia in the form of articulate storyline 3 is also effective in changing affective and psychomotor aspects in students. In the affective aspect, an average score of 44.9 was obtained with an average score percentage of 89.9%, this proves that the affective aspect of students has changed significantly with the very good category. In the psychomotor aspect, the results were obtained with an average score of 37.7 with an average score percentage of 75.4%, this proves that the psychomotor aspect students has changed significantly with the good category.
